damnsubaru Posted June 16, 2017 Share Posted June 16, 2017 the 93 legacy i am working on won't start it will spin over fine but no spark no fuel. i have power to the pump for a few seconds and power to the igniter and coils but no fuel and no spark. no check engine lights at all so no power to the ecm. chiltons doesn't help much as far as power and ground to the ecm. a checked the fuse all of them all ok working on getting the relays out but they are up there a ways. why can't they make them more accesable? got the ecm out and it smells like ozone. is that normal? can these ecm's be tested or do i just sustatute?

GeneralDisorder Posted June 16, 2017 Share Posted June 16, 2017 It's very rare to see a failure. If you are getting the fuel pump prime then the ECU is being powered. I would be looking at crank and cam sensor signals. GD Quote Link to comment Share on other sites More sharing options...

idosubaru Posted June 17, 2017 Share Posted June 17, 2017 They can fail but it's very rare. So rare that most people guessing, guess wrong and end up with a broken car and two ECMs. No power to the ECM sounds wiring related. Quote Link to comment Share on other sites More sharing options...
Subaru Scott Posted June 17, 2017 Share Posted June 17, 2017 I've seen a couple of cars that exhibited signs of ECM failure. Unplugged the connectors, untwisted/freed up any connectors that were in a bind. Made sure all wires were seated fully in the connectors and plugged back in, making sure all wires were free at rest with no side pull, etc. That fixed them. This should be one of the last things you do, the tips already mentioned above are much more likely to be the problem. Quote Link to comment Share on other sites More sharing options...

idosubaru Posted June 23, 2017 Share Posted June 23, 2017 Cam sensor is on drivers side cam, crank sensor is just above crank sprocket by crack pulley. Look it up online so you know what it looks like. Attached with one 10mm bolt. Quote Link to comment Share on other sites More sharing options...
